Supported data formats

QField supports a wide variety of formats via QGIS data providers and GDAL. This page offers a non-exhaustive list of supported data formats.


Data Format Support Notes
Postgis Ssl support not yet implemented.
Tiff ~ JPEG compression not yet supported.
ECW License restricts usage.
MrSID License restricts usage.

If you don’t find your favorite data format on this table, please check if it works and adapt the list above to share your findings. If it does not work, please open an issue. We will be happy to help you with the implementation.

Raster data

Raster data can become quite big quickly, when working with uncompressed tiff files it’s often several Gb of data. Especially on mobile devices, this is inefficient.

Use GeoPackage

We recommend to us the geopackage format to deal with raster data. The following commands will convert a file called raster.tif to a file raster.gpkg with pyramids. Make sure you adjust EPSG:21781 (CH1903 LV03) to your desired CRS.
